It differs from country to country, so any concerns should take that into account. For instance, in Sweden the total number of people that have died from 1 januari to 1 november this year is around 3000 more than the average during the same period in 2015-2019, which is lower than the 6000 official covid deaths. So it seems unlikely that there are a large number of unreported covid deaths hiding as something else.
